I am missing something really really obvious. The code below wires a gridview to a llblgends. Everything seems to work fine until I try to update values. Nothing changes and no errors are thrown. As far as I know with livepersistence its supposed the example should work. Bet I am missing something really pedestrian and obvious. I just cant tell what the heck it is. Do I have to manually wire up the controls that do the updating? If so, I could use an example. I traced the execution. Here is what it showed.

Method Enter: DataAccessAdapterBase.SaveEntity(4) Method Enter: DataAccessAdapterBase.DetermineActionQueues(7) Method Exit: DataAccessAdapterBase.DetermineActionQueues(7) Method Exit: DataAccessAdapterBase.SaveEntity(4): no entities to save.

Thanks in advance for suggestions.

Which llblgen pro runtime library versin are you using? What happens when you add a column for the PK?

I am using 2.6.8.1114 Adding a PK column to the gridview did not change the behavior at all.

Strange...I can't reproduce it.

Would you please use the latest build of the runtime library? Thanks

I got the latest runtime libs and they are the same version that I am using. Would be so kind and post your aspx code for your test? I want to compare it to mine.

Please download the ASP.NET databinding projet from our website(Customers Section - > Downloads).

sorry can you please clarify ... when you say " I can't reproduce the problem" how did you test it? Running a prefab example that we know works may not be the best test to determine why my aspx example doesnt. Can you please post your aspx that you used to test? I will also download the sample. Thanks.

First of all 2.6.8.1114 isn't the latest build. This is 6 months old, and we had many builds along the way.

I did write this prefab example, and it works against Northwind, and it's the one I always use to test databinding issues.

If you think is not good enough, then I'll have to ask you to provide me with a repro solution (better on Northiwnd or you'll have to supply the databse as well).

Seems we have a communication problem. I took a screenshot of the downloaded runtime files which contains a sql server dll that is the same version as I am using. Are you suggesting your download of RuntimeLibraries_05122009.zip has a different version than that? I will try to attach a screenshot. So I am not quite sure where you get the idea from that your SQL Server dll is a different version.

Secondly, based on your note that you can't reproduce the problem I thought you tried something with the aspx snippet I sent. Of course you cant reproduce an error with an application thats working. Do you see how I might get that impression? Maybe I am misunderstanding you?

I will take your suggestion and try the Northwind approach. Thanks in the meantime. Appreciate your feedback.

Walaa asked for the "Runtime Library Version", you gave the SqlDQE file version, which is different from the runtime lib. version. It's ok (it's the latest).

Would be helpful if you try to reproduce the problem in a Northwind app so we could talk on the same thing.

Now back to your problem, I suspect it's related to the fact the DataKeyNames are missing. Please read this: http://llblgen.com/tinyforum/Messages.aspx?ThreadID=4738&StartAtMessage=0&#25896

Thanks ! As I suspected ... a communication problem. Anyways I will test it out with Northwind. Between the posts and the samples there should be enough info to help me find my problem. BTW - the gridview has a DataKey set to the PK of the entitycollection. Thank you nonetheless for your reply. Much appreciated.

Hi, I'd like to know if there are some changes for using adapters and datasources recently? Because I've used them in version 2.5 and I've migrated in version 2.6 and I've the following exception: This DataAccessAdapter instance has already been disposed, you can't use it for further persistence activity Object name: 'DataAccessAdapterBase'.

I've verified but I haven't ude the adapter after callind=g Dispose(). So I don't know where comes from this exception. If you've some ideas about this? Thanks.

Hi wisedead, You have already opened a new thread for this question. let's proceed there. ref: http://www.llblgen.com/TinyForum/NewMessage.aspx?ThreadID=16162
